Erin McCarthy: Vegas Vampires

If you're looking for a light read, with a little humor and a little romance, try Erin McCarthy's Vegas Vampires series. From the jacket cover of High Stakes:
He's a bloodsucking freak of nature. But, unlike other politicians, Ethan Carrick is actually a nice guy. Not to mention a very hot, wealthy, casino-owning vampire. It's an election year for vampires, which means he'll first have to escape his opponent's hit men. Then he'll have to find a suitable First Lady, preferably here in Vegas.
Jane Austen, it is not, but McCarthy writes with wit and lighthearted humor, writing strong female characters that you'd want to go shoe-shopping with. The city of Las Vegas shines bright as a character in it's own right in the series, and her vampires are hunky, yet fallible and charming.

Christine Feehan is a favorite of many of my library patrons. Her vampire series is called The Dark Series, and it's dramatic, sweeping stories of romance and paranormal adventure. Not as light a read as I usually prefer, and much, much more spicy than my favorite Chick Lit titles. Feehan is a must-read for lovers of Laurell K. Hamilton, Sherrilyn Kenyon and Patricia Briggs fans.
From the book jacket: They are the Carpathians. For years, they have been persecuted by their enemies, and have struggled against all odds to preserve their species. Now, a new insidious plot has been devised-one that would slaughter Carpathian females and bring an end to all that the Carpathians have worked for. Even with his own lifemate, Raven, and their daughter Savannah, in danger, Carpathian king Mikhail believes that all is not lost. Gathering all of his people together, he will forge a new bond of strength, joining their powers in a celebration that will bring light even in this dark time.
